The Rotating Drum Dustiness Tester: Variability in Dustiness in Relation to Sample Mass, Testing Time, And Surface Adhesion

摘要

A rotating drum dustiness tester was used to characterize variability of dustiness in dependence of type and mass of test material, testing time, and surface face adhesion. Powders of six common materials entered the study: bentonite, barium sulphate, talc, Aloxite, carbon black, and coal. Except for coal, dustiness was in general positively correlated to the mass of powder under Testing. Surface adhesion tended to be affected from the type of test material.
